When you decrease the diameter of the stationary phase particles and make them more uniform, in HPLC, which term or terms of the
1 answer:
Answer:
C-term
Explanation:
A correlation between plate height and mobile phase velocity is known as the van Deemter equation.
Where;
H is the plate height
A is the eddy diffusion term
B is the longitudinal diffusion term
C is the resistance to mass transfer coefficient
u is the linear velocity
Here C-term describes the mass transfer of sample components between the stationary phase and the mobile phase during separation. One of the major factor affecting C-term is the particle size, changing the diameter equally changes the particle size.
The answer is C-term

The equilibrium constant is 0.0022.
Explanation:
The values given in the problem is
ΔG° = 1.22 ×10⁵ J/mol
T = 2400 K.
R = 8.314 J mol⁻¹ K⁻¹
The Gibbs free energy should be minimum for a spontaneous reaction and equilibrium state of any reaction is spontaneous reaction. So on simplification, the thermodynamic properties of the equilibrium constant can be obtained as related to Gibbs free energy change at constant temperature.
The relation between Gibbs free energy change with equilibrium constant is ΔG° = -RT ln K
So, here K is the equilibrium constant. Now, substitute all the given values in the corresponding parameters of the above equation.
We get,
So, the equilibrium constant is 0.0022.
